DUMP WAGON.

Specification of Letters Patent.

Patented June 6, 1922.

Application led June 13, 1919. Serial No. 803,925.

T o ali whom t may 00m-em Be it known that J oHN L; KoLBE, a citizen of the United States, residing at Crookston, in the county of Polk and State of Minnesota, has invented new and useful Improvements in a Dump Wagon, of which the following is a specification.

The object of the invention is to provide a dump body wagon suitable for farm use and adapted for the transportation of products and' materials of various kinds requiring modifications in the methods of handling; and further to provide a device for the purpose indicated in which the plane or aXes of the dumpingl movement may bemodified to suit the conditions of use and the characteristics of the material constituting the contents Vof the body; and incidentally toy provide an apparatus where either mechanical, horse or hand power may be employed in the operation of the mechanism necessary to the dumping movement of the body according to the conditions incidental to the use thereof.

With these and related objects in view as will appear from the following description of a preferred embodiment of' the invention the same consists of a construction, combination and relation of parts which, however, are susceptible of.' modification as to forms and proportion within the scope of the appended claims without departing from the principles involved. s

In the drawings:

Fig. 1 is a plan view of a vehicle embodying` the invention.

ig. 2 is a side view of the same, showing the depressible or dumping edge of the wagon body.

Fig. 3 is an end view showing the body in full lines in its normal and in dotted lines in its displaced or dumping position.

Fig. 4 is an end view showing the body in its dumping relation to the other parts in an elevated position as compared with that shown in Fig. 3.

Fig. 5 is a view similar to the Fig. 4 showing the body in an intermediate dump'- ing position.

Fig. 6 is a detail view of one corner of the dumping body.

Fig. 7 is asimilar view of one end of a frame wall to show the bearings for the body fulcrums which are interchangeable employed to secure the movement of the body to its dumping positions at various elevations.

Fig. 8 is a detail sectional view of the end wall of the dumping body substantially 1n the plane of the main fulcrum pin as on the plane indicated by the line 8-8 of Fig. 6.

The wagon frame may be variously con- *structed to suit the purpose for which it is intended but should include the end walls 10 and 11 which may as in the construction illustrated form the front and rear walls of the vehicle bed and a side wall 12 connecting said end walls, the opposite side of the frame being open to permit of the movement of the dumping body which, as illustrated, embodies essentially the end walls 13, the side walls 14 and 15 and the bottom 16, the latter being slatted or composed of spaced bars if desired. The outlet or depressible side wall of the wagon body may be fitted with a movable tail gate 17 hinged as at 18 and normally held closed by latch 19 engaged with a catch 2O carried by the bottom of the body, said latch being-operable by means of a rod 21 accessible to an attendant standing at one end of the structure when the wagon body, for example, is in its tilted or discharging position.

In its normal or carrying position the wagon body is supported by means of runners 24 bearing upon rests 23 consisting of bars disposed longitudinally of and close to the lower edges of the end walls 10 and 11 of the wagon frame, as shown in Fig. 7, said end walls of the body iitting between the rest bars to give stability tothe structure.

Carried by the end walls of the wagon frame between which the tilting movement of the body is effected there is a plurality of bearings located at different locations and severally designated as 25, 26, 27 for the reception interchangeably of fulcrum pins or studs on the body to form the axes of movement of the latter as it is tilted from the normal to the dumping position, said bearings being arranged at different elevations and being formed of, straps or brackets and being arranged preferably in different vertical planes as specifically indicated in Fig. 7. Fixed to the end walls of the wagon body are the fulcrum pins or studs 28 which are adapted for engagement with the bearings 25 and into which they naturally drop or move as the body is rocked from the normal or carrying position indicated in full lines of Fig. 3 toward the position indicated in dotted lines of said figure. Vhen in the normal or carrying position said fulcrum pins or studs occupy seats 29.

Mounted on the discharge end of thefbody are the rods 30 fitted in suitable guides 31 and connected with bolts 32 which form fulcrum pins o r studs when projected beyond the end edges ofthe side wall, the adjacent extremities of said rods 30 being connected to an operating lever 33 which when in the full lineposition indicated in Fig. 2 serves y to hold the bolts in their retracted or housed positions, which, when 'in the dotted line position a in said iigure serves to project the bolts into positions where their terminals constituting the tulcruml pins or studs will engage the bearings 26, and which when in the dotted line position Z) in said Fig. 2 will still further project said bolts to cause their terminals constituting` the ttulcrum pins or studs to engage the bearings 27.

Thus when the tulcrum pins 'or studs 32 are withdrawn or housed the tilting move? ment ot the wagon body will be upon an axes determined by the engagement of the v fulcrum pins or studs 28 in the bearings 25. When the lever 33 is adjusted to the position indicated by dotted lines a oit' Fig. 2, the tilting movement of the body will'be with reference to an aXis determined by the engagement ot the fulcrum pins or studs 32 with the bearings 26, whereas upon a tull extension ot the bolts 32, eti'ected by the movement ot' the lever 83 to the dotted line position shown in Fig. 2 the tilting movement of the body will be with reference to an aXis determined. by the engagement-ot the fulcrum pins or studs '32 with the bearings 27. Said bearings 25,26, 2T being at dierent elevations, it is obvious, that the elevation ot the discharge side or tail gate of the body with reference-to the plane o' the wagon trame will be regulatabie by the use of one or the other of the meansdescribed for determining the axes ot dumping movement, to suit the conditions under which the wagon may be operated or-the character ot' the material which is being handled.

The means for effecting the tilting movement of the body consist ot the tilting levers 34, fulcrumed as at 35 to the end walls oil the wagon frame and terminally having sliding connections with the dumping body. The body, for example, is provided with guides 36 and the levers with pins 37 tor traversing the guides, there being means for swinging said levers from the vfullline position A indicated in Fig. 3 tothe dotted line position B in the same figure, Obviously the means tor actuating the tilting levers may be variously modified, but as illustrated, consist of cables 38 preferably connected with the extremities of the levers as at 39, designed to give a substantially uniform leverage during the movement ot said arms, and guide or direction rolls Ll0 around which the cables extend to the point of application of power which may be either mechanical., horse or hand as may be desired. lt is preferable as shown in the drawings to provide the cables with an lintermediate traction loop Ll1 to which a team may be connected, and also to use in connection therewith a drum 42 having a crank 43 so that when the use vof horsepower is undesirable or impossible by reason of vlimited space, the tilting movement of the body may be ett'ected by hand power, but it will be understood that the drum or drums for this purpose may be located wherever it may be most convenient to the operator, taking into consideration the purpose 'for which the apparatus is designed, and as will be understood, either at the ends of the frame or at the side thereof. The return of the body to its normal or carrying position be effected either by hand power or otherwise, as by grasping the free edge ot' the body or by attaching thereto a rope which may be manipulated from the ground at a point near the vehicle. Obviously after the body has been moved 'from the dumping position a short distance towards its normal position its weight will return it to its position on the bed, such movement being controllable by tension on the operating cables 38 regulated by the operating drum. Rising from the end walls ot the supporting frame there are provided the uprights or standards le Vforming hitching posts which are commonly employed in connection with devices oi this kind and which serve as means also ttor attachment ot retaining ropes to extend over the load contained by the body when there is a possiblityo'lz displacement of the latter in transit.

The invention having been described, what is claimed as new and useful is:

1. A dumping body wagon having a supporting trame provided with end walls, a tilting body mounted tor movement between said walls, the Yframe being provided with rest bars and the body with runners for engagement with said rest bars, t'ulcrum pins or studs on the body adjacent extremities of the runners, open topped bearings on the end 4walls of the trame Yfor the reception of said fulcrum pins or studs, and means for effecting the tilting movement of the body.

2. A dtunping body wagon having a supporting irame provided with end walls, a tilting body mounted therebetween, said body being provided with end runners and the end walls of the trame with rest bars tor supporting the same, ulcrum pins or studs projecting terminally from the body,
